Can anyone explain to me why recently, some of the profile options are appearing as...glitchy?

For example, there are some fields where members can pick a sprite/image to represent them. It isn't the avatar, it's a totally different field I added.

Anyway, sometimes when I view someone's profile page (or my own) it will show ALL of the options even when I don't click anything to edit it. It also will display random text field boxes, and show some of the images as the image source code.

It's really odd, and apparently other members in my forum have been noticing it too.

This is a separate question, but why do some member names appear in italics? At first I thought it was because they were the newest member, but now it seems to happen randomly.
